Question

1. I have a NSMutableArray named as records and a NSArray.

2. Now I am retrieving an XML attribute and its value, using TBXML parser and inserting the attribute value in the NSArray.

3. This NSArray is an object of records.

What will be the numerberOfRowsInSection when I want to display the value of XML data in tableview cell?

This is my data retrieving procedure….

[records addObject:[NSArray arrayWithObjects:
    [TBXML textForElement:id],
    [TBXML textForElement:productNumber],
    [TBXML textForElement:name],
    [TBXML textForElement:availableStock],
    [TBXML textForElement:image],
    [TBXML textForElement:quantityOrderMin],
    [TBXML textForElement:dateCreated],
    [TBXML textForElement:dateUpdated],nil]];

And my XML data are….

<ProductData HASH="21106941">
    <id>1</id>
    <productNumber>a91cc0f4c7</productNumber>
    <name>Product 1</name>
    <seoTitle>product-1</seoTitle>
    <viewCount>0</viewCount>
    <availableStock>100.0</availableStock>
    <lowStock>0.0</lowStock>
    <image>5e928bbae358c93caedf6115fa7d178b.jpg</image>
    <quantityOrderMax>20.0</quantityOrderMax>
    <dateCreated>2011-10-06T16:08:45</dateCreated>
</ProductData>
<ProductData HASH="409555632">
    <id>2</id>
    <productNumber>d8287e2e51</productNumber>
    <name>Product 2</name>
    <seoTitle>product-2</seoTitle>
    <description>
    <p>Lorem ipsum dolor sit amet, consectetue...</p>
    </description>
    <viewCount>0</viewCount>
    <availableStock>100.0</availableStock>
    <image>8bbd8dfff3cdd28285d07810a4fe7c32.jpg</image>
    <quantityOrderMin>1.0</quantityOrderMin>
    <dateCreated>2011-10-06T16:08:45</dateCreated>
</ProductData>

I am being able to retrieve data in UITableviewCell, but it’s displaying first two retrieved data of the NSArray because the number of rows are two in records array. but i want to set the numberOfRowsInsection will be according to the total number of attribute value retrieved by NSArray.

I have got the problem and I know the problem is here:

  - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
        NSLog(@"The number of row in the object array:  %d ",[records count]);
        return [records count];
    }

How can I fix it?
